Earth's Internal Structure
The 3 layers of the Earth.
What is crust, mantle, and core?
The layer of the crust that the lithosphere (plates) float on/move around on.
What is the asthenosphere?
This type of push causes sea-floor spreading.
What is a ridge push?
The 3 types of plate boundaries.
What is convergent, divergent, and transform?
Rock changes shape from stress (tension & compression).
What is deformation?
This layer includes the crust and upper mantle.
What is the lithosphere?
Developed the Theory of Continental Drift.
Who is Alfred Wegener?
When hot magma rises and cooler magma sinks?
What is convection?
Compression forces occur at this type of plate boundary. Reverse faults also occur at this boundary.
What is convergent?
The 2 mountain chains found in the U.S. that are examples of folded mountains.
What are the Appalachians & Rockies?
The type of energy transfer that takes place in the mesophere.
What is convection?
Name of the giant supercontinent that formed on Earth around 250 million years ago.
What is Pangaea?
At a subduction zone, a denser oceanic plate slides beneath a continental plate.
What is subduction zones, trenches, volcanic eruptions/mountains, and/or earthquakes?
A normal fault occurs at this type of boundary.
What is a divergent boundary?
On Monday, this lab will demonstrate how the asthenosphere has the consistency of a liquid.
What is Oobleck Lab?
Name 4 of the 10 major tectonic plates that cover Earth.
What is South American, North American, Nazca, Cocos, African, Eurasian, Pacific, Indian, Australian, Antarctic?
The Marianas Trench occurs at this type of zone.
What is a subduction zone?
The Great Rift Valley in Africa is an example of this type of mountain?
What is fault block mountains?
The layer of the Earth that is the thickest.
What is the core?
List 4 pieces of evidence used to back Continental Drift.
What is similar coastlines between continents (puzzle pieces), similar rocks, similar fossils, glacial grooves, similar climates, similar mountains, GPS mapping measuring distance and direction of movement?
When a slab pull occurs, crust is pulled into this layer of the Earth.
What is the mantle?
Yellowstone and the Hawaiian Islands have formed because they are sitting on top of this geological feature.
What is a hot spot?
Name of the national park in the continental U.S. that is sitting on a hot spot.
What is Yellowstone?
